You collapse, feeling very thin yet stretchy but you realize you have no sense of your arms or legs. That is nothing when you realize you have no head, and no insides, limp on the floor until slender fingers pick up up and you see Gina smiling as she hold something, holds you! How light are you now? She races to the mirror and holds you up in front of it, and you would gasp if you had lungs or a mouth as you see your girlfriend holding a shimmery blue pattered swimsuit. You! She giggles "You came out perfect, now let me try you on." she goes into the bedroom and lays you on the bed, then reconsiders and drapes you over a chair. That confuses you as to why, but then she starts to get undressed, and she is doing it super slowly...a strip tease for you and she wanted you to see. This is such a turn on, but you have no body to in fact turn on, and its all in your mind, but with no ability to release like this, you're just spandex lycra! Her motions and perfect and so alluring...your mind lurches as you realize she is doing a strip tease, but when done she is going to do a strip dress, or dress tease, or whatever the hell it would be called as she puts YOU on. You would need a cold shower right now if you had a human body, hell you would need to Arctic ocean.
She is finally naked and sways her way over to you, and it is the best sort of torment knowing you are going to on those hips swaying with her very soon. She lightly picks you up laying you against her naked torso, dancing with you in front of the mirror, making sure you get another good look at your new self. Then she bends over, placing you on the ground, slowly stepping a foot into you, then out, in then back out, finally in, and then the other one in, and she very slowly shimmers upright, all the while sliding your crumpled form up her long lean legs.
She makes a big show out of seeming to struggle with pulling you to her hips and crotch, but does so, patting you on her womanhood, before taking both hands and squeezing her ass in your thin form. She then slowly slides an arm down into one side, then the other.....dancing and wiggling a bit, sliding you up her torso, but then with a shout, she jumps up, brings her arms up fast and you snap into place on you, fully stretching and assuming her curves. She did that so well that if she shot you with the other device and you were now a swimsuit forever you would be happy.
She sways and moves over to the mirror "Hope you liked that babe, and while I know you can't talk, I can't wait to wear you on the beach, laying out to tan. Might even need some studly man to rub lotion on me, and if his hands sneak a squeeze or a grope, you'll be the first to know" she blows a kiss at the her reflection and then packs a bag for the beach, while you try to concentrate on not losing your mind to the sensations of being this snug to her body, with no other outside distractions.
